Given numbers are 780, 815, 364, 451

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 815 are 5 x 163

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 451 are 11 x 41

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 780, 815, 364, 451

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(780, 815) = 127140

GCD(780, 815) = ( 780 x 815 ) / 127140

= 780 / 815

= 780

Step2:

LCM(5, 364) = 1820

GCD(5, 364) = ( 5 x 364 ) / 1820

= 5 / 364

= 5

Step3:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

So, Greatest Common Divisor of 780, 815, 364, 451 is 1
